Letters Patent No. 106,692, dated August 23, 1870.

IMPROVEMENT IH PARLOR-ORG-ANS.

The Schedule referred to iu these Letters Patent mnd making part of the same To all whom i t may concern Be it known that I, EMMONS HAMLIN, of Winchester, n the county of Middlesex and State of Massachusetts, have invented au Improvement iu Parlor- Organs; and I do hereby declare that thc following, taken iu connection with the drawing which accom-' panies and forms part of this specification, is a dcscriptiou of my invention sutlicient to enable those skilled iu the art to practice it.

My im'ention-relates, particularly, to the construction of that class of reed mnsical instruments known as cabinet or parlor-orgaus.

I-Icrctoi'ore it has been customary to make these instruments of a rectangnlar form, or box-shaped, iu horizontal cross-section, the length of the instrument corresponding to, .or nearly to, the length of the key-. board.

In my iI-nprovcment I add, at each end of the main body ol' the instrument, a chamber, the outer walls of which are 'ormed by extension of tbe main walls or casing of the organ, the upper portion of these chambers, by their resonnnt properties, increasing the tonennd the quality of the tone of thc instrument, without mari-ing its appearance, the front of thc case being made, as heretofore, of a length to correspond to the key-board, and being joined to the end walls of the added chamber by suitable connecting wood-work or panelin lt is iu a parlor or cabinet-organ, made with these auxiliary end chambers, that my invention consists.

The drawing represents an instrinneut embodying my improvement.

A shows a front elevation.

B, a horizontal section on the line a: 1'.

a denotes tbe main body or oasing of the instrument, iu the lower part of which are the pcdals and bellows, and in the upper part thc swell, wind-box,

.reeds, &c.

l) is the key-board, projecting iu front of the casing, as seen at B.

c is tho chamber over the soninling-lnnird, such board forming the bottom of the chamber.

Beyond each end of this chamber I form the auxliary chambers e c, by lcngthening the main body or casing beyond the key-board, this being ettected without lengthening the body at the front, and by extcnding the soumling-board preferably to the end walls g, as shown.

These chambers c e l cover at their top, the cover not being shown iu the drawing, and, beneath thc walls h, they communicate and form oue with the. principal chamber c.

I also make graceful connections between the front workor wallf and the walls g.

I thus add two resonant chambers, c, (ot'great value iu giving tone and power to thc instrnnicnt,) without detracting from the appearai'ice of the casing, the extensions i'ormed by thc additional chan'ibers breaking up the square lines and corners, and improving the appearance as well as the musical properties of tho instrument.

I claim- ,Iu combination with the chamber c, the anxiliary chambers e, formed in the cxtensious of the body or casing of the instrument, substantially as shown and described.
